本文通过对钢珠式离心自炸机构的受力分析,得出离心钢珠在自炸前的运动中可能存在两种运动方式,推导出两类自炸角速度ω~T的计算公式及控制运动方式的条件。通过精度分析提出了控制运动方式的必要性及选择较佳参量、拟定优化设计目标函数的方法。 In this paper, through the analysis of the mechanical behavior of the ball-type centrifugal self-blasting mechanism, it is concluded that there may be two kinds of movement modes of the centrifugal ball in the movement before self-frying. Two formulas for calculating the self-blasting angular velocity ω ~ T and the method of controlling the movement condition. Through the analysis of accuracy, the necessity of controlling the mode of movement and the selection of better parameters are put forward, and the method of optimizing the design objective function is proposed.
